JOHN A. HOLLENBERGER, OF HAGERSTOVN, MARYLAND, ASSIGNOR OF ONE- FOURTH TO TOBIAS SCHLOSSER, OF SAME PLACE.

DOOR-LATCH.

$PECIFICATION forming part of Letters Patent No. 336,810, dated February 23,1886.

Application filed October 31, 1885. Serial No. 181,495. (No model.)

To all whom it may concern:

Be it known that I, J OHN A. HOLLENBERGER, a citizen of the United States of America, residing at Hagerstown, in the county of \Vashington, and State of Maryland, haveinvented certain new and useful Improvements in Door- Latches, of which the following is a specification. reference being bad therein to the accompanying drawings.

The object of my improvement in door latches is to'avoid the jar and noise incident to the slamming of doors in forcingback the latch, and to render unnecessary other efiort in closing and latching a door than is requi-' site to swing it on its hinges, and also to avoid the loosening of rim-lock keepers and the usual injury to which looks are subjected from violent and repeated slamming of the doors; and my invention consists in the peculiar construction, combination, and arrangement of the parts, substantially as hereinafter more fully shown and described.

In the accompanying drawings, Figure l is a view in perspective of a door-latch to which is applied the devices embodying my invention. Fig. 2 is a sectional View. Fig. 3 is a detail view;- and Fig. 4 is a sectional View on the line 00 as, Fig. 2.

In accomplishing the objects ofmy invention I pivot button B by means of journal-pin A on the face-plate A, as shown. Button B has cast integral therewith lug O, which projects horizontally from its lower edge, as shown. The pivoted button B fits flush against the lateral front face of the door-lock, and the lower lateral edge of the button is arranged to avoid frictional contact with tongue D. Journal-pin A has cast integral therewith button B at one end and the metallic disk B atits opposite end, and said pin A is inserted in corresponding horizontal re ces, F, formed in face-plate A, and when thus inserted the metallic disk B, which projects across said recess,holds and guides in its movement the button 13. The horizontal recess F is closed when the lock-plate G is secured to the lock by means of the corresponding plate-lug,d, projecting at right angles from said lock-plate, to which it is rigidly secured,

and which fits into said recess. Lug dis provided at its end with the semicircular indentation d, which is adapted to the round periphery of journal'pin A.

The button B, which is pivoted to swing freely in a position vertical to journal-pin A and parallel to disk B, is constantly retained in its proper position. It is prevented from being inadvertently swung out of position by means of disk-pin e, in connection with stoplug f on lock-plate H and a corresponding stop-lug, g, on plate G. These lugs may be screwed into threaded orifices provided in the lock-plates or be cast integral therewith.

My improvement may be applied to either a rim or mortise look; but when applied to a mortise-lock the length of the button is such that in closing the door the latch enters the mortise or keeper at the moment when the button, which is held back by the door-jamb, is released from the door-latch.

Thus constructed and arranged button B, on opening the door, swings freely into a vertical position by means of its own gravity,and rests in shoulder 1), formed in door-latch E, and this prevents the latch from being projected out by its latch-spring inclosed in the lock and obviates the need of slamming or otherwise violently forcing the door in closing it.

As it is obvious that tongue D of the doorlatch is not absolutely essential to the operation of my improvement in doorlocks, I do not restrict myself to its use, as shown and de scribed.

Having thus fully described .my invention, what I claim, and desire to secure by Letters Patent, is

1. In a door-latch, the combination, with the face-plate A having a slot, F, and the plates G and H,having rigidly secured thereto lugs g f, respectively, of the pivoted button carrying a lug at its lower end, and having a journal secured in the said slot of the face plate A, lug d,secured. to plate G,disk B, secured at one end of said journal and carrying a disk-pin, and door-latch E, substantially as shown and described.

2. The combination of button B,having pin A,disk B, having pine, and stop-lugs f and g, with lug d, and the latch having a tongue 10 rigidly secured, respectively, to locleplates H formed on its outer face, substantially as shown and G, substantially as shown, and for the and described. purpose described. In testimony whereof I affix my signature 5 3. In a door-latch, the pivoted button havin presence of two witnesses.

ing 3. lug secured at one end and pivoted by a 1 JOHN A. HOLLENBERGER. journal secured in a recess of plate A, said Vitnesses: journal having secured to its inner end a disk,
